Patented Dec. 28, 1915.

Application filed June 24, 1914. Serial No. 847,100.

i T all whom it may concern Be it known that I, WALTER E. COPI- THORN, a citizen of the United States, residing at N atick, county of Middlesem st'ate of Massachusetts, have invented an lmprove-' ment in .Ri-ms for Vehicle lvheels, of which 1 the following description, inconnection and particularly to wheels adapted for use as truck wheels, and the invention has for its object to provide a novel 'demountable.

rim which is simple in construction and can be, read ly removedfrom or replaced on the wheel and. which has other advantages that embodiment thereof which will now be dewill be more fully hereinafter set forth.

In order to give an" understanding of the invention I have llustratedherein a selected scribed-after which the novel features of the invention will be pointed out in the appended claims.

Referring to the drawings, Figure l is a side View of a vehicle wheel embodying my invention; Fig. 2 is a section on the line can, Fig. 1; Fig. 3 is a sect on on the line e '1 ,.Fig. 1; l is asection on the line a=a, Fig; 3; Fig. 5 is an enlarged section on the line b.b, Fig. 1; Fig. (i is a perspective view of one of the locking wedges; 7 is a sectional \lOW on substantiall i' the line c 0, Fig. 8; showing my invention as can bodied iir'aftirc with a block tread: li is a section on the linea -4i, Fig. 7; Fig. 9 is a sectional view showing 111v mvcution embodied in a. dual tread tire; Fig. 1G. is a detail of the filling, ring shown in -1 t);

have shown at l a wheel body having any suitable or usual construction which is provided with the usual folly 2 which is encircled by the felly band 3.

4 is the tire and this maybe either a continuous tread tireor .a -blo'ck tread tire'as desired. The tine is mounted on a dem'mm'table rim which isihehlon the wheel between two ail'l'uila'r members 5 and fi'situat-ed on opposite'sidcs of the wheel. herein shown the demountable rim is made in two sections 7 and 8 which are separable from each other and in Figs. 2 and 3 each section of the dc mountable rim is provided with a side flange 9 which overlies the side of the tire. The tire 4 is made with a. wire 10 extending longitudinally thereof preferably substantially in its center and with cross wires 11 which have interlocking engagement with the de mountable rim and serve toprevent the tire from creeping. These wiresll are shown 6 as secured to the annular wire 10 preferably A by extending through said annular wire, although'they may be secured to the wire 10 in any suitable way. Said transverse wires 11 extend beyond the sides ofthe tire 4 and v enter sockets or openings in the demountable 'rim. Inthe construction shown in Figs. 2 and 3 these sockets. or openings are shown at 12 and are formed in the flanges 9. Further, in the construction shown in these figures the two sections 7 and 8 of the demountable rim are provided with overlapping portions 13 at. their adjacent edges and they are secured together by a bolt or screw l-l which extends through these overlapping portions, and also extends up-into the wire 10. These bolts 14, therefore, not only hold the sections 7 and 8 together, but form an additional means of securing the tire to the rim. The two parts '1 and 8 of the demountable r m are placed at a slight angle to each other, and situated between each part of the' domountable rim and the felly band 3 is a filling ring 15 which is tapering, from the outer to the inner edge. These filling rings 15 will preferably be split rings so-that they can expand or contract slightly, and will thus always hug the felly band 3 tightly.

The annular members 5 and 6 are each preferably split, and the memberfiis made removable So that item be readily aken off to provide for removing the 'demountable rim from the wheel. As stated above I will preferably make both members 5 and 6 in two parts, but it is not essential that the MS member 5 should be. thus made. Thelannu' lar member 5 is held in positio"by means of bolts 16 extending transversely through the rim, and inthe illustrated embodiment of the invention these bolts occupy recesses 200 formedin the periphery of the felly 2 and are situated directly underneath the folly band 3. \Vhere the member 5 is a two part member I prefer the construction .18 and 23 as best seen in l i 4:.

- construction to the wedge member shown in Fig. 4. wherein each end of each part is provided with the taperingv surfaces 1.! which are engaged by a wedge member 18, there being two wet g'e members engagingthe two ends of each section of the memher 5,. said wedge members being held firmly in place by the bolts 19. The annular memher 6 is removable to permit the. demonn'teble rim to be removed, and this member is shown as provided with slots 22 which are of esize to'permit the heads 20 of the bolts 16 to pass therethrough, one edge of each shot havii'ig the inclined surface 21 adapted to engage underneath the head 20.

- The twosections of the member 6 ere ebsoutely necessary in securing the .ring' sections in place.

To remove the demoiin'tehle rim. the'nu't 27 on the bolt 19 is removed, thus permitting the wedgememher 2-3 to be removed after which the ring sections 6 cenbe shifted lcngitndineliy to permit them to be disengaged from the heedsBO of the bolts 16 and thus removed. When this is done and the wedge member 26 has also been. removed, then the demounteble rim can be readily taken oil all) from the wheel.

In locking the demoimtable rim on-the wheel the ring sections 6 are placed over the heads '20 and after the wedge member 26 has been clamped in position, then thewedge I member 23 is forced home thereby acting on r a block tread tire.

the inclined faces 24 of the members 6 and "moving them longitudinally into locking engsgement with theheads 20, as shown in Fig. 5.

In order to prevent the demountabie rim from creeping, I provide'the Wedge mem' bers. 18, 23, 26 with laterallyextending noses 30 which overlie the folly band 3 end are received in recesses formed in the underside of the'dcmonntable rim sections 7 8.

In Figs. 7 and 8 I have shown a different embodiment of my invention which is per ticulerly adapted for use in connection with In this embodiment the tread or rubber tire & is made in separate sections 40 which can be independently re moved from the wheel rim if required. Each tread section 4 is provided with a longitudinal wire 41 extending from one end to the other thereof with transverse wires e2 which are secured to the longitudi nal wire, preferably by extending therethrough. The ends of these transverse wires 42 extend through openings "i3 formed in the two sections '50, 80 of the demonntol'ile rim and the ondsof the transverse wires 43 project slightly beyond the rim sections 7 80 and intorecesses it formed in the filling ring sections 150. The demcimtable rim is held in place on the wheel between the two annular members 5 and 6 as above described, the member 6 being rcadily detachable to permit the tire to be removed. In this embodiment of the invention the Wires ii. are anchored to the demounteble rim by'means of screws 46, the shanks of which extend through and occupy half recesses formed in the meeting edges of the rim sections 7*) and 80. With this construction it will be seen that if any tread section 40 becomes demaged and needs to be replaced, the locking member can be removed and the adjacent fi ling ring 150 is then tnlren off from the wheel, after which the rim section can be readily withdrawn, this being possible be; cause the two rim sections 1 0 and 80 are not comic d together as in. Fig". 2. After the rim secnon. 80 is removed, then any desired tread section d0 can be removed from the wheel and replaced by a new trend section,

after whicl'. the "i550 and loch position. engagement between the ends of the WilQS 43 and the recesses ll serve to hold the separate tread si'rctions 40 firmly in their proper position.

In Fig. l. have illustrated my invention. esembcdied in a duel tread tire. The construction shown in Fig. 9 is the same as that shown in Fig. 8 except that two trcncs are rim section 80, filling ring ring 6 can be replaced in Bil screwed-6. together with the employed and t filling ring 700 is used between the adjacent rims.

I claim: i. In a wheel, the combination with e wheel body, of c demounteble rim encircling seid body, split filling rings situated between the rim and wheel body and centering said rim, a locking; ring for holding the demhnnt able rim in position, and :2. locking member for the locking ring, which member has interlocking engagement with the demounb able rim.

2. in a wheel, the combination with a wheel body, of a demo'unteble rim encircling said body, positioning and locking rings se cnredto the wheel body and holding the rim in place, said locking ring being formed of two' tmrts, and a wedge member engaging seid'two parts and locking them in position, seidwedge member having means to interlock with the rim to prevent the letter from creeping.
